In BFDI, Ice Cube wanted to join Pencil's alliance multiple times, to which Pencil always refused, much to Ice Cube's distress. Although, when Match was eliminated, Pencil finally excepted her into her alliance. However, Pencil claims that Match is way better than Ice Cube and proceeds to call her garbage compared to Match.
In BFDIA, Pencil excludes Ice Cube from her alliance for making an "ugly face". Later in Insectophobe's Nightmare 3, Ice Cube is eager to join Pencil's alliance once again, to which Pencil responds saying that she can be an alternate. In Get in the Van, Ice Cube joins FreeSmart, along with Book and the rest of Pencil's alliance.

In BFDI, Blocky has killed Ice Cube a number of times. For example, he melts Ice Cube in order to win the contest in Crybaby! This didn't end up paying off in the end. In Insectophobe's Nightmare, Blocky made a contraption to infinitely kill Ice Cube using a tree, a spring, and her recovery center. At one point in another episode, Blocky tried extinguishing a fire with Ice Cube which was caused by Pencil and Match.
